  1. 1. Spherical Crystallization of Benzoic Acid

    Författare :Jyothi Thati; Åke Rasmuson; Luis Moreno; Eva Blomberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spherical agglomeration; Spherical agglomeration; Benzoic acid; Solubility phase diagram; Physico mechanical properties; Chemical engineering; Kemiteknik;

    Sammanfattning : Spherical agglomerates of benzoic acid crystals have been successfully prepared by drowning-out crystallization in three solvent partial miscible mixtures. Benzoic acid is dissolved in ethanol, bridging liquid is added and this mixture is fed to the agitated crystallizer containing water. LÄS MER

  3. 2. Engineering synthetic pathways for adipic acid biosynthesis

    Författare :Jae Ho Shin; Chalmers tekniska högskola; []

    Sammanfattning : Utilization of petroleum in consumer product manufacturing is causing irreversible environmental damage. Its impact on land, sea, and air calls for the development of more sustainable technologies based on the use of renewable materials such as lignocellulosic biomass and its conversion into platform chemicals.

  4. 3. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Författare :Xiomara Holmbäck; KTH; []
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER

  7. 5. On the Influence of Mixing and Scaling-Up in Semi-Batch Reaction Crystallization

    Författare :Marika Torbacke; KTH; []
    Nyckelord :reaction crystallization; precipitation; benzoic acid; macromixing; mesomixing; micromixing; semi-batch; loop reactor; backmixing; colour experiments; scaling-up;

    Sammanfattning : Semi-batch crystallization experiments have been performedboth in a loop reactor and in stirred tank reactors.Hydrochloric acid was fed to a stirred solution of sodiumbenzoate, and benzoic acid immediately formed. Benzoic acid isformed in excess of the solubility making the solutionsupersaturated.The loop reactor is U-shaped. LÄS MER
